I guess we this explains quite a bit.
I thought this was kinda obvious all along. It's just been another placebo, like so many other things people do with their phones (wipe data AND cache x3 times!).
Your battery runs out when there's no more power in it. Stats have no effect on that whatsoever.
The only thing I ever used wiping battery stats for was if it appeared the battery wasn't being reported correctly, like never showing 100% charged when it was fully charged, or dying before it got to 0-1%. It never was meant for anything other than that IMO, despite people using it as a cure all.

The premise if the article is incorrect. The primary purpose is to get a more accurate reading if software was flashed on a less-than-full battery charge; nothing more nothing less. Anyone who ever thought it had any other purpose was simply misinformed. With that said, after reading the info in that link, I checked and the battery stats are indeed wiped automatically whenever the battery is fully charged and the cable is removed. I wonder if this behavior began with gingerbread or if this is old news.

The "13 steps" thread at the top of this General section looks sort of funny now after hearing this news.
I would think that a live wallpaper, turning the phone on and off and phone calls, data, wifi do most of the battery kill... battery stats, just doesn't make any sense. What proof is there that wiping the Dalvik cache does anything either? Does flashing roms at 100% mean anything either? I really don't believe it matters... never did. Just sounds like a theory, not a fact.

I am very sorry to open a new thread about battery drain that has been discussed so many times but I am really desperate.
I recently purchased a second hand Nexus S i9020A (unlocked AT&T version) from swappa. (Website that sells only android phones) and I am getting terrible battery life no matter what I try.
The phone is rooted and have tried several ICS roms and all have terrible battery life about 6-7 hours when the phone is on idle for most of the time.
I then installed CM7 as I read that ICS has some battery drain issues, but I still get really bad battery life 6.5-7.5 hours again the phone is on idle for most of the time.
I also tried several kernels.
I tried disabling the WIFI, GPS etc this did not help.
The phone came with two batteries an Anker Battery and the Samsung battery. I sent Anker an email asking them about the battery life, they told me to let the battery discharge to around 10% and recharge to 100% a couple of times. I did this twice, but no improvement in the battery life I was about to do it a third time when I fell asleep the battery must have drained completely and now that battery seems to no longer be working.
I thought maybe I am really unlucky and I got two bad batteries, so I purchased a new RND Battery from Amazon as I thought maybe there were some problems with the Anker. Turned off the phone let it charge for 7.5 hours, but the battery meter still showed that it was not fully charged, but the instructions said to charge for at least 5-6 hours, so I turned on and unfortunately I have the same battery drain.
I have installed a Battery Calibration app from the Android Market to see what the reading was and when the phone read 100% charge it was a little over 4,000 mV . I am not sure if this is what it is supposed to be, maybe one of you can let me know.
In addition I have wiped the battery stats from from the bootloader a few times after I have fully charged the battery and even factory reset the phone but this made no difference.
Last night I even flashed a new radio I went from I9020AUCKF1 to KB3 but this also made no difference. I have been struggling with this problem for about a week with no improvement what so ever.
I read that its bad to completely discharge Li-on batteries, so before I left home to go out, I turned off the phone so that the battery would not discharge, when I arrived home a few hours later the battery was dead even though the phone was turned off. (this was the original Samsung battery not the new battery I purchased, I did not try this with the new battery as yet)
I checked the battery usage and compared it to a Galaxy S2 to see what was using up the battery and the OS and Screen usage % seems to be comparable amount to the GS2.
I also tried a few of the Governors that are included with CM7 and also used the wheatly Governor when I was on ICS, but it made no difference.
Can any one help me? Is there something wrong with the phone? I purchased this as a present for someone who really wanted an iPhone because I could not afford an unlocked iPhone and they are really disappointed by this. I know this may be an isolated case, but I always assured the person that the android phone can do everything the iPhone can do, but not I feel like such a fool.
Can this be fixed? I purchased this when I was in the US but now I am away so returning it would be a problem. Is there a way to check if there is something wrong with the phone itself that's causing the battery to drain at such a fast rate?
Any one that can help me I would really appreciate it and be very thankful, I know there are other topics that deal with battery issues, but I have been researching this for about a week and tried everything I can, I didn't just start a new thread without trying.
The screenshot below shows a high display usage because I was using the phone to try to troubleshoot normally android system uses the most and display is closer to 7% but the uptime is the same. Even though it says 3h 51 mins at 48% in the screenshot the battery seems to discharge faster as it percentage goes down.
Can you enter this code and check for battery information:
*#*#4636#*#*
You can check the battery health and temperature. It might give you some insights.
Do you have good reception? Is it constantly trying to connect to 3G networks? Can you check apps which might be trying to connect to Internet all the time? Do you have this problem once you flash a clean rom (or maybe it starts after installing apps)? Have you tried stock ROM?

Hi Oogway first of all thanks a whole lot for your response.
I dialed the number and got the following
Battery Status : Discharging
Power Plug : Unplugged
Battery Level : 100
Battery Scale : 100
Battery health : Good
Battery Voltage : 4096 mV
Battery Temp : 34.0 C
Battery Technology : Li-ion
Time since boot : 9:58
Just finished charging it again.
I have good reception, but I have no data plan on this phone so it isn't using any 3G, actually I don't even have 3G in my country :|
I have no apps installed and the problems still happen even with a clean install. Before the person shipped the phone to me I asked them to install the stock rom and when I got it the problem was present, since then I tried different roms but to no avail so far.
Thanks very much for your time and effort in offering possible solutions, I am grateful for your help.

Its not a new phone its a used phone, but the seller has agreed to refund me if needed, the problem though is that I bought the phone in the US but I am not in the US now, if I return it to him he may be charged taxes etc.
I returned the phone and radio to stock, but it seems the issue is still present. Any more ideas?

I have abyssmal battery as well with my used i9020t. Although I have only used various ICS so far and don't know how used the battery is.
At night I put it to airplane mode and closed running apps. In the morning the phone feels warm and battery drained drastically, which makes no sense.
I just got an Anker battery as well and will try some Gingerbread rom. For now I'm using Franco kernal and undervolting by 50mV which help a bit, but not much.

Hi Bedalus, I bought it on swappa. I bought a few phones there before without any problems. I have a paypal receipt from swappa, maybe I can email samsung and find out if they can repair or not. I honestly think its a hardware issue now. Because the battery still drains even when the phone is off. I flashed several radios and roms, wiped battery stats, changed battery, wipe data and factory reset and its all the same.
My issue though is that I am not in the US and the phone was purchased from the US so return may be a problem as well as shipping to Samsung, but I will email them to find out more.
But thanks for your suggestion Bedalus, really appreciate it.

Hi Ekasol, does your battery drain even when the phone is off like mine? How much battery life do you typically get? I get around 6 hours. Just to let you know that I did flash the stock ROM on the phone but it made no difference to me.
Mine is the AT&T version, I got the roms here .. http://forum.xda-developers.com/showthread.php?t=1445621
But you can get the roms for yours here http://forum.xda-developers.com/showthread.php?t=1063664 in case you have not found the original roms yet. Best of luck, I hope at least one of us is able to get the phone working or repaired.

Bedalus, before I contact Samsung, do you know if rooting and installing custom roms void the warranty?
Technically yes. However, if you wipe, install a stock rom and bootloader and lock the bootloader afterward, they have no way to tell.
Thanks Harbb
Can you try this Gingerbread rom NSCollab anyway, I know you said you tried GB already. I don't have time to test with full battery yet, but Gingerbread seem to retain battery life pretty well.
If you still have time, I would say save yourself the hassle and return it, it sounded like hardware issue. And buy the person an iPhone instead. If he/she is not tech savvy it is pointless and will just give the person a difficult time. I do not have an iPhone, but I have to do iPhone tech support for my co-workers, Android would just be a nightmare.
Also if the person don't mind going with T-Mobile, see if you can return it and get a Galaxy S 4G. It is one of my favorite phone. No LED flash and ICS (yet), but you get microSD slot and HSPA+ 21Mbps (cheaper plans too). And best of all the Valhalla roms.
Tried NSCollab, battery drain seems to be a little worse with this ROM. The reason I did not purchase the iphone is because of the cost, I got this for around $260. Thanks for the suggestions though, I will consider them, but so far it looks like this phone has some hardware problems.
I was on GB and had amazing battery life!
Just flashed AOKP milestone 6 and I can can't watch
The battery drain.
I've read forums and not much help.
I DL better battery but don't really know how to use.
I tried formatting battery stats.
Any solutions?
I am having the same issue. I am going yo try cMIUI. what are you getting for battery life?
Sent from my SGH-T959V using xda premium
Are y'all sure it's not just because you're doing lots of stuff with your phone right now, having just flashed a new ROM?
If it's an extreme amount of battery drain, it might be some leftovers from whatever you had last. You could try a factory reset and then see how stock AOKP handles battery drain.
I know I don't get battery life as good as I did with Octane, but a big part of that is because I've been flashing the new AOKP builds every couple of days, so things don't get a chance to settle down. (Granted, battery life still isn't as good as when I just flashed Octane.)
There is tons of things regarding this very issue in the AOKP q & a thread. Please use the search this thread button in that thread. Ive typed a response atleast four times today. And atleast four yesterday and more the day before and the day before that. NOt trying to be a ****, but Im tired of typing and responding. If you cant be bothered to read the thread or search I cant be bothered to respond anymore.
Not sure for sure.
But I get 5-6 hours on full charge with medium use(text. Instagram. Web.)
How can I get exact info?
Read the AOKP Q&A, yes, the whole thing
Read the OP's instructions on the AOKP dev thread
Read the thread on Bettter Battery Stats
Listen to what people say about battery use
Think about what you have done and what to try next
Do
Rinse
Repeat
Ask yourself "Why am I flashing ICS at all?" -- ICS in the SGS4G is still very much in development.
I don't think you realize how unreasonable it is to ask someone to read that entire Q&A. I've followed the thread from its beginning, and there's no real solution to the battery issue being described here. You'd only be wasting everyone's time who took your advice. I've also read all of OP's instructions in the AOKP dev thread, and have even tried the gremlin remover prior to flashing AOKP. This does not solve the battery issue. You're seeming to imply that the battery issue is the user's fault, and I think that's not even remotely close to the truth. I've done multiple flashes, each time trying something different, to see if I did anything to cause the horrible battery in AOKP, and they all concluded the same way. With that said, we need to actually try to fix this, instead of sending people in circles and pretending to fix it.
First of I dont have battery issues at all with AOKP I am a User a very grateful user (thx 2 our devs). Just factory reset, after that wipe cache, system, everything except your sd card of course) and the flash your rom. Its really a matter of re-assuring everything is wiped. Also leave your phone alone for awhile I left mine around 2 hrs alone, while the rom settles.

Go to the Gremlin Remover dev thread, and try steps 1-3. If you are STILL having exaggerated battery loss, try using gremlin remover it'self. If you still have problems, after making it back to your preferred rom, just put the phone down for a while.

Some of us are getting good-very good battery life, and some of us are not - using the same exact ROM. I don't know what that tells you, but what it tells me is that it *is* likely to be a user issue.
People complain about battery life, but they hardly ever talk about the total time they are using it (including fiddling around with it), what programs they have used or have installed, and how they are restoring after they flash (i.e., if there is a chance they are bringing along bad stuff from a previous incarnation of the phone). More information about these things and - yes - doing tedious things like the process of elimination might be enlightening here.

Ya know when I first came here I said something similar. But Ive kept up with these threads now and I know for a fact battery life issues have been discussed to a point that the devs are ready to pack up and leave. Nobody wants to read or even search. Instead the battery life issues are blamed on the shotty coding of the people building these roms. If you are getting bad battery life it is plain and simple a user error. Unless you can provide logs stating otherwise then just drop it try what is being suggested or go back to stock roms. Install all the apps you need to customize the phone like it is on the ics variants and then report back here. I garandamntee you will have ****ty battery life.
These custom roms have so much stuff added to them that is hard coded in for customization that its not going to have super battery life like a unbloated stock rom. But you cant expect it to. A good comparision was made earlier in another thread. Would you expect to get 8 hours out of a laptop battery?
I always tell people to make sure to completely drain the battery....all the way until it shuts off, because mine will sometimes stay at 1% for nearly 2 hours.
Seems like it doesn't know its own scale until you do that a few times.
Also never ever ever restart this phone while having it plugged in or turn it on while plugged in.
Let me give you the scenario, it will be charging let's say around 50% and then after restart while plugged in right around 75-80% and that little act took me a long time to recalibrate my battery and I'm not talking about deleting the battery stats, I don't delete battery stats anymore at all (read an article from Google saying its pointless)
All that said I'm a very heavy user, and I like a bright screen and I'm getting (what I would consider) good battery life. But I have a 3500mah so its never too bad for me
Hope this helps someone

I'm on AOKP, and my battery life is GREAT. There are plenty of steps and tips mentioned here to find out what your battery problem is.
I would like to see screen shots of the battery usage of people that have crappy battery.
From home hit menu>settings>scroll down a bit to battery.
Take two screenshots one of the initial screen, then touch the graph at the top and take one of that screen.
I keep hearing battery life is horrible I only get 4 hours, please fix this, hows battery life..blah blah blah battery. Yet nobody will drop usage stats, logs of a days use, offer anything but i use my phone moderately. I call bull**** on that, How many texts do you get/send in a day? How long are you on the phone making calls? Do you live in a poor service area? Give some info.
On a average day I get about 50 texts, might make a 20 minute call, use tapatalk a half dozen times, and use tweetcaster and flipboard a dozen times. I can get 12-15 hours out of a full charge. To me that is light to moderate use. I get crappy data where Im at right now so Im on wifi A LOT. When Im actually using t-mo data more I can get closer to 18 hours out of a charge
People if your having problems with battery life stop rebooting the phone a hundred times a day. Stop shutting off all the radios thinking it will help. use the dang phone like it was meant to be used. None of the code is optimized for people to shut radios off and turn the phone into a dumbphone. You are making it worse by shutting these things down and turning them back on. It takes power to properly shut off bt, wifi, data. Next time you do watch the radio will not just instantly shut down. It has to power off all the service that is using it and then power down. Otherwise you would be here *****ing about tons of force closes.
I get about 17hours on my phone and i have a stock battery. I use all the extras PROVIDED TO US BY THE DEV like turn off wifi/date off or to 2g while phone screen is off. Auto bright and all the extras.

My phone usually drains 10% each 5hours of sleeping (air plane mode). Is that normal? I can get around 3hours of web surfing,which is less than it was on SCOM (4hours).

My phone has been acting really weird the last few day. I had [ROM][MTD]CyanogenMod 9.0.0-rc2 UNOFFICIAL by TeamAcid[R5][Jul-20-2012 installed on my phone. But it would crash all of the time. Afterwards when the phone rebooted the battery would go from 100% to 9%. If I dont boot the phone back up right after a crash and wait a little while. When I boot it up the battery will be around 40-45%. I used [Heimdall][One-Click] The T959V Heimdall One-Click Collection [05/20/2012] earlier today, Just to see if I continued to have the battery problem. I only had the phone crash once while on the stock rom, and the battery did drain about 50% but I also started having a problem where I would lose my data connection all together. Rebooting the phone brought it back, only to lose it again after around 30min to 1hr. It has not crashed for about 3hrs now and I have not lost my data connection either. Anyone have any ideas what might be going on here? I tried deleting the battery stats with the battery at 100% before going back to stock but that did not seem to help at all. I downloaded a batter calibrator from the market place and tried that as well. Used it when the battery was at 100%. None of this has worked. Now that im back on the stock rom its only crashed once, but the battery did still drain. Any ideas? I would really like to go back to CyanogenMod 9 but its not worth it if the phone continuously crashes and kills the battery. Any help would be greatly appreciated.
Try Gremlins Remover.

So you don't waste any more time, "battery calibration" is snake oil, lithium ion batteries don't need "conditioning" (and actually suffer from both high temperatures and deep discharge cycles), but the moon is made of cheese. Ok, at least the first two are true.
As you're having problems with one of the most stable and reliable GB ROMs for this phone, I suspect that you may have one or more of:
Bad battery
Bad user-land applications
Corrupt application data
Corrupt media data (for example, music on your microSD)
Bad phone
Bad luck
A "start over" approach with a complete clean-out either using the above-mentioned one-click, or doing the equivalent by hand (wiping all partitions, flashing stock, starting with a fresh microSD), then seeing how the phone/battery behaves without any apps would be the path I would take. If it passed that, I'd slowly start adding back apps, and only restoring data/preferences where you really need them.
Im doing the gremlin remover right now. I will let you guys know how to goes. Thanks for the advise, this has been driving me crazy.
Tried the gremlin remover last night and played with my phone today. Its still crashing and then when I boot it up back the battery is pretty much dead... I think i have a bad battery. Never had these problems with the phone before. Thanks for the help guys. I guess Ill get a new battery and see if that fixes the problem.
I have this EXACT same problem. I'm on AOKP and the battery with go from having a decent charge and die. Then if I take the batt out, hold the power button for 15 secs and let the phone sit with no batt for 10 minutes or so, the phone will go back to around 50% batt life. After gremlin remover and Bryan's one click back to stock multiple times, I've finally come to the conclusion that I need a new battery.
I ordered a new battery today. I will let you know how it goes.

So I looked I to this issue more. For anyone having this problem, remove the battery and place it on a hard flat surface to see if it has swollen any, if it has then the battery is defective. My battery actually rocks a little. I could actually tell it had swollen before I even put it on my desk.
That is only for seeing whether a cell has busted. It is normal wear and tear. That is kind of like how u lose battery life after hundreds of cycles because it is just how the current li-ion battery technologies work.
I would download the one click and also reflash boot loaders and repartition your device.

Tried that, even with bootloaders. OP also stated they used gremlin remover as well. As we we're both having the exact same problem, I was giving him a better solution that wasn't the standard "reflash, repartition, etc."
I finally got my new battery in. And all is well now. Thanks everyone for the advice and help

thats crazy swapping you battery worked. lol, mine does it too. not so much the crashing just a simple reboot and it will be drop down from 70% to 1%. This was doing the same thing with my phone before my charging port got busted. So i had to swap out the guts from my old galaxy s with broken screen. When i put the new internals in i started with bh's one click back to stock and flashed antonx kernal. Then flashed cm9 and it still does it. i will try a new battery as well.
My thought (AFTER being solved)
Well, I don't mean to come off as rude, but come on guys! I've had this problem for a while, and as soon as it happened I knew I needed a new battery. On top of my phone being somewhat "old", the fact we all play around with it so much, and do so many battery pulls most likely does NOT help the matter. At least I screw around with my phone and try out many ROMs...
But I'm glad I have confirmation that a battery swap will do the trick. It sucks that stores don't carry the t959v battery anymore... Guess I'll be ordering online tonight.
I'm having issues of the phone rebooting by itself and consequently draining ~90% of the battery when it does so. I've tried flashing a bunch of different ROMS to see if I can stop it from happening, but to no avail. I'd like to go completely from scratch and hopefully I can get to a point where the phone works for an entire day without crashing. I've been using the HD2 instead of the SGS4G for a couple months now, so I'm a bit rusty, which is why I came here to ask for suggestions. This is what I was planning on doing:
- Flash one of these stock ROMs in order to get back to where I started.
- Format my SD card completely and let the phone convert it back to EXT4
- And then flash either Barebone or Valhalla
Do you guys think this would be sufficient enough to remove the problem that's causing these reboot & battery drains?
I would flash eollies kj6 with the blastoff v2 if your not planning on going to ics after because that's the latest gb kernel available and then flash Valhalla or barebones (then you might have to flash blastoff again can't remember right now but it should say in the op of each rom). And I'm pretty sure when you one click back to gb that will convert back ext4 so I would format SD card and reload it before you one click back. Good luck friend

Thanks for your input! Do you think the gremlin remover is necessary, or is it overkill in the context of what I'm doing?
If you want quick and easy use my one click the other two listed is just kernels.
As for getting battery life on ICS flavored roms, well take the time using BBS and STT to figure out whats killing your battery. As long as Im not jumping between wifi and mobile data I can go around 15 hours on a battery. And I havent spent tons of time to figure out why Im not getting more battery life. But others like jeffsf has. And with that I can honestly say if your not getting battery life comparable to GB roms its YOUR fault not the rom. Most ICS roms have stuff built in that you have to use a app for. Therefore a GB rom with nothing installed will get better battery life. But once you put your stuff on and start running the battery life is not being compared properly. The reason for this is most people will keep a app just because they are use to it and not even know the ICS rom has it built in.
I personally think most of our batteries - if still using the one that came with the phone - are starting to run their course. New batteries are inexpensive on Amazon.
I think you guys are misunderstanding my issue. My problem isn't the battery draining quickly over a certain amount of time due to regular use. My problem is that once my phone crashes and reboots, the battery will literally go from whatever percentage I was at, all the way down to below 10%. I can be at 90% battery, and if my phone crashes, it will be on low battery once it powers back up. I'm not sure what's causing the crashes, which is why I'm just trying to start at step 1 and work my way from there.
To test if it was the battery simply draining out very quickly, I turned brightness to 100% and turned WiFi & GPS on, and disallowed the screen from turning off. The battery drained normally.
That happens to me... It gets fixed by shutting down and taking out the battery for 30 seconds.
Sounds like a bad battery
i had the same issue and also would get diff battery levels when booting with or without charger plugged in...i used a toool from market to calibrate battery. i cant remember exact app but will post back if i find it.
edit:
it was "Battery Calibration"

and i had to do it a couple of times to get it to set in.
Like thecontroller stated its a bug and you should be able to correct it by pulling the battery out and waiting a few extra seconds. If it does it still hold the power button down for a little while with the battery out.
Do this next time you have a crash on ics. Time how long it takes for the phone to restart. It is seems abnormally long you could have some scripts that are running on boot that is causing issues.
Calibrating the battery can be done manually. All you have to do is delete the batterystat.bin file. That is all those apps do. And really If you fully charge your battery it should be deleting itself.

In a nutshell, yes. You are only putting extra stress on your battery by "tricking" it according to various calibration guides. Batterystats.bin file is generated for a reason. Batterystats.bin is in /data partition, so after you install a new ROM that wipes your previous data, it gets wiped too. So, "Wipe battery stats after installing a new ROM", which is a cliche among those guides, is pointless. Last but not least, batterystats file is simply a logging tool that monitors your battery behavior. The "stats" part is pretty self-explanatory. The actual Power Manager lies in kernel, not in /data partition which accessible to anyone.
SBD all that info is true. But if you use the aroma installer it will backup and restore the data partition. Not sure if it will restore the batterystat.bin file or not. That is why I posted what I did. I do not believe in calibrating batteries as much as making sure they file is not storing data that is out of date.
As you guys mentioned earlier ...hard resets are the best ....I find our batteries do go bad. And when they do....they do all kinds of odd things to the device

Battery calibrations are garbage. They do nothing. The file that any battery calibration app deletes is deleted by Android anytime you do a full charge anyway.

Not to mention the screen. Was in Costco last week, saw the old T959V on display and held mine up to it. Screen is faded bad I don't know if any of you else have noticed that lol

Okay, so I formatted my SD card, and flashed Eollie's KJ6 using Heimdall. After that, I flashed Raver's Valhalla Black.
Initially, I didn't install anything extra other than updating gmail and superuser. Everything worked fine, apart from one random reboot. Once it booted back up, everything was normal. Today, I installed around 5 apps. I was using one of those apps (Reddit Is Fun), and while using it, the phone crashed. Once my phone booted back up this time, everything force closed, and log provider force closed over and over. I had someone text me, and right after they did my phone just crashed. I tried fixing permissions, but that didn't do anything.
Any suggestions?
--edit--
I just factory reset and tried reflashing Valhalla Black, but everything just force closes again even on a fresh install.
Boy I don't know what the hell you're doing but you are doing something very wrong.
Flash back to stock (complete stock). http://forum.xda-developers.com/showthread.php?t=1358498
Then flash AntonX http://forum.xda-developers.com/showpost.php?p=19601810&postcount=2
Once you do that, flash a ROM.
I just went through the same issue. This was going on rarely for several weeks then got more frequent. I have a couple of extra batteries that T-Mobile sent me when I first got the phone....swapped in one and its been 10 days without a single issue. Before posting here tonight I put my old battery back in and guess what? Symptoms came back within 30 minutes....so....

Then there's your answer, you need a new battery my friend
Just so weird, I don't see how a battery can affect the OS in that way haha. I've ordered a new battery anyway, they're only like $5 on Amazon, but I'm gonna try your steps anyway, controller. Thanks a lot guys.
